• − The font looks more like a digital brush than natural chalk handwriting.

FLUX.1 Kontext [dev]

• + Excellent adherence to the specific 'horse on top' spatial instruction
• + High clarity and clean rendering of both the horse and the astronaut's face
• + Correct interpretation of the 'surreal' aspect by subverting physics.

• − The background is somewhat plain with simple spheres instead of complex space nebulae.

Stable Diffusion 3.5 Large

• + Beautiful cinematic lighting and atmospheric effects
• + Highly detailed environment with nebulae and planet curvature
